Iron-catalyzed
hydrogenation has drawn much attention, yet the
scope and chemoselectivity of iron catalysis warrant further improvement.
Here we report new iron pincer complexes as chemoselective hydrogenation
and transfer hydrogenation catalysts. Several Fe(II) complexes supported
by a 2,6-bis(phosphinito)pyridine ligand (PONOP) have been synthesized.
Fe(II) hydride complexes [(iPrPONOP)Fe(CO)(H)Br]
(2) and [(iPrPONOP)Fe(CO)(H)(CH3CN)](OTf) (3) can activate H2 at room
temperature. Complexes 2 and 3 are hydrogenation
catalysts at room temperature, and the hydrogenation is selective
for aldehyde in the presence of ketone and alkene groups. 2 and 3 are also chemoselective transfer hydrogenation
catalysts using sodium formate as the hydride source.
